SPRAYING- DEVICE.

To all whom it may concern Be it known that we, HERBERT DANIELSEN,FREDERICK A. HAAsE, Jr., and JOHN H. B. SHANNON, citizens of the UnitedStates, and residents of Newark, in the county of Essex and State of NewJersey, have invented a certain new and useful Improvement in SprayingDevices, of which the following is a specification.

The present invention has for its object an automatic disinfectingapparatus which is simple of construction and positive in action, andconsists of an atomizer, together with an automatically operatedreciprocating air or other gas pump having a relatively quickcompression stroke and a relatively slow return stroke forintermittently and at regular intervals creating a momentary blast ofair, said air blast being led to the atomizer. Means are also providedfor varying the timing of the return stroke and at the same timemaintaining the pressure of the blast constant, thereby varying thefrequency of the intermittent blast.

Figure 1 is a front elevation of the apparatus with its cover removed.Fig. 2 is a sectional side elevation, the section being, taken along theline 33, whlch shows the pump in half section.

In the figures like numerals designate corresponding parts.

In Figs. 1 and 2, the numeral 1 designates a box or case having a cover2, Fig. 2, said case 1 being so constructed that it will contain andsupport the other parts of the apparatus. The pump casing 5 is supportedby means of the brackets 6 and 7 which are fastened to the back of thecase 1 by means of the screws 8. The solenoid cylinders 9 and 9, onwhich are wrapped the coils 13 and 13', are supported by the insulatingblocks 10 and 10, 11 and 11'. A means of support for the blocks 10 and10, 11 and 11 is formed by cutting grooves in the rear and side walls ofthe case 1 into which the blocks 10 and 10, 11 and 11 fit and arefastened by means of the screws 12. To the bottom of the insulatingblocks 10 and 10 are fas tened, by means of the screws 14, the bindingposts 15, 16 17 and 18, which hold the wires 19, 20 and 21, which willbe described hereinafter.

Specification of Letters Patent.

Application filed June 4, 1913.

Patented May 19, 1914. Serial No. 771,609.

The solenoid cores 22 and 22 have an upward and downward motion throughthe cylinders 9 and 9' as the current is respectively made and broken bymeans of the switch described hereinafter. These solenoid cores 22 and22 are flanged near their ends, as shown at 23 and 23, and are fastenedsubstantially to the cross-member 24 by means of the nuts 25. At thecenter of the cross-beam 2 1, is fastened the piston rod 27, being heldin place by means of a screwfastening 28, which is attached to thecrossbeam 2 1 by means of the screws 29. At the other end of the pistonrod 27 is a shoulder 30 which supports the rubber plungers 31 and 31,that are held to the rod by means of the nuts 32.

At the end of the pump case or cylinder 5 is secured the plug 33, whichcontains the outlet tube 3 1, and the intake plug 4:. The intake plug 4has cut in it a V-shaped slit 38, through which air is admitted to thecylinder 5 on the intake or return stroke of the pump, which is effectedby gravity as will be more fully described hereinafter. As the intakeplug 4 is screwed farther and farther down into the end plug 33, lessand less of the V-shaped slit will be exposed above the surface of theplug 33, and smaller and smaller will become the opening through whichthe air is admitted to the cylinder 5. Thus by screwing the intake plug4: into or out of the end plug 83 we have a means for regulating thespeed with which air enters the pump cylinder 5 on the intake or returnstroke of the piston, so that the duration of the intake or returnstroke which is accomplished by the falling of the cores 22 and 22, iseither quickened or prolonged by screwing the intake plug 1 respectivelyinto or out of the end plug 33.

The atomizer 37 shown in Figs. 1 and 2 is of the type in which airpassing through a tube which leads from the pump cylinder 5, is blownacross the end of a tube which leads from the reservoir of the atomizerthus causing a vacuum to be formed and inducing a stream of liquid toflow, which, when it meets the blast of air in an external nozzle 39 inFig. 1, is broken up and blown outward into a fine spray which isexcellent fol-disinfecting purposes: But the particular pattern orcharacter of the atomizer forms no essential part of my invention. Theatomizer is supported by means of a block 32, which fits into grooves inthe rear and side walls of the casing 1 and is fastened by means of thescrews 12. The bottle or reservoir of the atomizer is held in place onthe block 32 by means of the spring 40, which 44 isof suitable form tohold the carbon.

47, which is fastened to the switch plate 44 by bending the sides of theplate "in, as "best shown in Fig. 2. The upper carbon contact piece 48is held in a similar mannera-s 47 by the upper switch contact pieceplate '49, which ls-screwed to thelink 50 by means of the screws 51. Thesaid upper switchplate 49 is in the form ofa spring so that whentheswitch is closed it willpress its carbon contact piece 48 against thelower contact piece 47 sufficiently to form a good electric contact.

The link 50 is made of a suitable insulatin'g material and issupport'edon a pin 52 which is driven through the link 50 and which is held in'the'bearing brackets 53, as 'shownin Fig. 2, the saidbearing brackets53 being fastened to the rear 'wallof the case 1 by ine-ans of screws 8.The link rod 54 which has an eye at'each'end is fastened by means ofpins 55 and 56 to the ends of the aforesaid link 50 and a link '57. Thelink 57 fastenedat its other end to a bearing bracket 58 by means of apin 59 in amanrner similar to which the link .50 is fastened to thebearing bracket 53. The bearing bracket 58 is fastenedto the rearwall-of the case 1 by means of the screws- 8. The aforesaid li'n'k'57has a cross-bar 61, shown best in Fig. 1, to which are fastened thesprings 60. The other end of the said springs 60 are held by eyes62,.Fig. 2. To the cross-rod 24 is fastened-by means ofthe screws 63 aplate 64 which pushes against link 57 when tlTQ'SOlGIIOIdS are raisedand starts the link 57 onits upward motion; which, when it hassufficiently passed its dead center, with respect .to the springs 60,will continue to move upw-ard'by virtue of the elasticity of the springs60 until'it comes in contact with the rubber bumper 65 which is held bythe bracketti.

In the operation of our device current enters through the fuse box 66and is led along-the insulated wire 19 to the binding post 15, fromwhich it is carried around through the coil 13 to the binding post 16,.through the insulated wire 20 to the binding post 17 then around throughthe coil 13, from here to the binding post 18, then through theinsulated wire 21 to the upper switch plate, and hence to the uppercarbon contact piece 48. The circuit is completed when the switch isclosed, bringing the upper contact point 48 and the lower. contact point47 together and permitting the current to flow out through the bindingpost 46 through the wire 67, through the fuse and hence back into themain line.

Supposing the switch to be closed, the: current passes through thesolenoid cores. 13 and 13, thereby quickly drawing up into the cylindersSand 9 the cores 22 and 22 and imparting a relatively quick compressionstroke to the piston r0d27. As the cores rise they carry with them thecross-bar 24 which, as the cores near the top :of their stroke, raisesthe link '57 by means of the plate 64, pushing it sufficiently so thatit is carried farther by means of the springs 60, as heretoforedescribed. As the link 57 moves upward around its pin 59 it drags withit. the link 54, which in turn raises the lever 50 upward around. itspin 52,thereby opening the switch and thus cutting off the current. thecores 22 and 22 reced'e' from the coils 1.3 and 13, due to the force ofgravity, carrying the piston rod 27 down with a relatively slow returnstroke,and :whenthey reach the end of their downward stroke they againclose the switch, since the cross-bar 24 "to which they are attachedthen" rests on the link 50-and the weight ofthe cores is suflicient toovercome the; tension ofthe springs 60. As soonas the switch is closed,current passes through the solenoid coils, the cores are raised, andwhen they reachthe end of their upward stroke they again *open .the'switch, as before described, and thus the cycle goes on repeatingitself. The raising of the solenoid cores gives compression stroke topump which furnishes air to the atomizer. The intake or return strokevof the pump, the duration of which can be regulated by means of thep1ug4, as heretofore described, serves not only to bring sufficient airinto the pump c'ylinder5 but by retarding the fall of the solenoid coresserves to regulate the frequency-ofthe discharges of disinfecting fluidfromtheatomizer. The variation in frequency of the blast, as above'described, nevertheless maintains the pressure'ofthe blast constant.

What is claimed, is:

1. A spraying device comprising an atomizer, an automatically operatedreciproeating air pump having a relatively quick compression stroke anda relatively slow return stroke for intermittently and 'at'regw' As soonas the current is shut off lar intervals creating a momentary blast ofair, and means for leading said blast of air to the atomizer- 2.
